A critical discovery about how bacteria feed on an unusual sugar molecule found in leafy green vegetables could hold the key to explaining how ‘good’ bacteria protect our gut and promote health. Leafy greens are essential for feeding good gut bacteria, limiting the ability of bad bacteria to colonise the gut by shutting them out of the prime ‘real estate’.
Researchers identified a previously unknown enzyme used by bacteria, fungi and other organisms to feed on the unusual but abundant sugar sulfoquinovose (SQ) found in green vegetables. Each year, leafy green vegetables eg, spinach – produce the sugar on an enormous scale globally. The discovery could be exploited to cultivate the growth of ‘good’ gut bacteria...
